PORTLAND, Maine -- Nearly 10,000 years ago, man's best friend provided protection and companionship - and an occasional meal.
That's what researchers are saying after finding a bone fragment from what they are calling the earliest confirmed domesticated dog in the Americas.
University of Maine graduate student Samuel Belknap III came across the fragment while analyzing a dried-out sample of human waste unearthed in southwest Texas in the 1970s. A carbon-dating test put the age of the bone at 9,400 years, and a DNA analysis confirmed it came from a dog - not a wolf, coyote or fox, Belknap said.
Because it was found deep inside a pile of human excrement and was the characteristic orange-brown color that bone turns when it has passed through the digestive tract, the fragment provides the earliest direct evidence that dogs - besides being used for company, security and hunting - were eaten by humans and may even have been bred as a food source, he said.
